This invention relates to a mowing machine comprising a blower forsubdividing the stalks. It has been proposed to separate the stalks tobe cut from the others by a blower. This invention has however for itsobject to make the blower act, after the lifting of the cut stalks, andfor disentangling and separating the same.

According to the invention this effect is obtained by continuouslyelevating the cutstalks by conveying plates and to expose the same tothe action of the blower shortly before they are deposited upon theplatform,

the air current from the blower passing through two sheaves of cutstalks to disentangle the same and to separate one sheaf from the other.A further characteristic feature of the invention consists in arrangingthe conveyingor elevating-plates on the circumference ofstar-wheels orthe like, between which the blower drum is situated the outflow openingof which isobliquely directed in upward direction.

An embodiment of the invention is shown,

byway of example, in the accompanying drawing in which Fig. 1 shows theimproved mowing machine in sectional view, the front side wall beingomitted.

Fig. 2 is partly a top view and partly a section on line 2-2 of Fig. 1.

Fig. 3 shows the connection of the grippers with the star wheel and theblower drum on a larger scale.

Fig. 4 showsthe star wheel in combination with the mechanism foroperating the lifting platform.

Fig. 5 shows the grooves for guiding the pins of the sprocket wheels intheir complete 40 length. I

Fig. 6 shows how the sprocket wheels are arranged.

Figs. 7 and 8 show details of'the means for operating the grippers.

In the side walls a of the mowing machine running on rails 79 a drum mis fixed which is open at the top end at c and which forms a blowerowing to the arrangement of a vaneinechanism d, fixed on an axle erotated in 5 0 the drum by any suitable driving gear and 204,612, and inGermany July 13, 1925.

which throws an air current through the oblique upwardly directedopening 0 of drum m. At either side of the blower drum m rotates a diskor star-wheel is, said wheels having several, in the form ofconstruction shown seven corners, and further a toothed crown meshingwith a spur wheel Z drivenin a suitable man ner from the outer side ofthe ma chine, said star wheel being slowly rotated around thestationary'blower drum in the di- 0 rection indicated by the arrow linesin Fig..- 1. On each of the seven corners of the star wheel is a"conveyer-plate j is pivotably mounted which'is subdivided into twoportions similar to a hay turner,so that the conveying-' orelevating-plates circulate at the rotation of the star wheels around thestationary blower drum. The conveyingor elevat- V ing-plates j are eachcomposed of a top portion 39 and of a lower portion 9 hingedly'connectedthe one with the other and further of. steerable gripper-tongs r. o Onthe end wall a (Fig. 3) of the stationblower drum m three rails, groovesor guide bars 8, 8 s are arranged at unequal distances from the axle ofthe drum and being each of a differentcurvature,while on all these sevencorners of the'star wheel, betweensaid wall a and the star wheel, threesmall-size sprocket wheels 6, t are arranged the axles u, 10 M2 of whichare journaled in the star wheel. A pin 'u, 0 e on the rear side of eachsprocket wheel t, t 6 respectively' engages with the corresponding guidegroovess s so that, whenthe star wheel is rotating, they movealong thecurves of the guide grooves whereby the sprocket wheels 6, 6 t can moveto and fro in accordance with the curvature of the grooves or bars 8, s

The three sprocket wheels 25, t and t (Fig. 6) carry chains 8 which areguided over sprocket wheels 25 on shaft Z, the extreme one of thesesprocket wheels 6 being keyed on this shaft to rotate the same, wherebythe 7 part 79 of the conveyer plate y is pivoted. The two other sprocketwheels 73 are mounted on hollow shafts and transmit this rotatingmovement through sprocket wheels mounted on hollow shafts at the side ofthe sprocket wheels Z by means of chains 3 onto two sprocket wheels tmounted on a shaft P, the extreme one of these sprocket wheels rotating.the shaft Z and thereby the lower part g of the lifting platform, whilethe rotation of the sprocket wheel at the side, by means of a sprocketwheel at the side of the same and by means of a chain a, is transmittedupon a sprocket wheel 6 and thereby upon a shaft Z and upon the grippertongs 1'. These griper ton s r are 0 )eratedin such a manner that theends 1" (Fig. 7) of the gripper tongs, pivotally mounted on a beam 1'engage with oblique grooves of a control cylinder q rotatably mounted onan axle Z in thelower of this cylinder, the gripper tongs 1 areoscillated, as indicated in Fig; 8 in dash dot lines. At therotationofthe sprocket Wheel part 9 of the lifting platform so that, at therotation of the control cylinder, the gripper tongs a" are positivelyopened and closed. An extension 7 of beam r is guided in a slot Q3 (Fig. .8) of the part 9 of the lifting platform and connected by .a spiralspring r to acontrol cylinder 9' so that, at the rotation i 7) on theshaft Z the gripper tongs 7 close owing to the rotation of the controlcylinder g, as the'arms r of the gripper tongs are spread asunder by thegrooves Owing to the connection of theextension r of the beam 1"? by thespiral spring 1" to the control cylinder g"'tliebeain r will pivotaround this extension r as far as the slot Q3 permits and withoutpreventing continuing of the rotation of the control cylinder andletrated between the fingers y and cut by the knives, have to beseparated to groups f, g, h,

.the one behind the other, as shown in Fig. i.

According to the invention the first group or sheaf h is gripped by thetongs 1 of the lowermost conveyingor elevating-plate j which .is instretched position, and is elevated, when .the rotation of the starwheel continues,

around the stationary blower drum by the conveying plate which continuesto move with the star wheel. In the course of the continuing rotationofthe star wheel the up per and lowerportions of the elevating plate aregradually folded over more and more, so

that they are finely lying the one on the other.

vIn this position the group h of stalks arrives over the obliquelydirected outlet opening 0 of the blower drum so that it arrives in therange of the air current from the blower m, this air current passingthrough between this group of stalks and the next following group andseparates the one group from the other,

and disentangles the stalks. The separated group of stalks h is firstsupported at its upper portion by a movable platform 0. When therotation of the star wheel continues the lower portion 9 of theelevating plate pivots around its pivot pin 12 to assume the stretchedposition indicated in dash-dot lines, while the platform 0 continues toniove into the position 0 indicated in dot-lines. This being effected,according to Fig. 4;, by the cylinder T which, rolling on ls,'oscillatesat the rota- 7 tion of is by means of the rods T the levers 7' hingedlymounted on the lifting platform 0 and thereby this platform itself. Thewhole group 71 of stalks is thus pushed upon the plat form 0 and is Wellseparated-from the next following group of stalks. Allt'he tongs 1" arereleased at the same time, the group it and the conveying plate 7' infolding over in downward direction, continuing to move in the mannerdescribed.

The constructional details of the conveying plates 7' and of thegrippers r are not shown in the drawings to avoid complicating of thesame.

c A binding apparatus mightfurther be con- '90 nected to the deliveringdevice so that the delivered sheaves :2 can be tied'up'at once. Thesheaves may be deposited at the side of the machineto clear the pathalong which it travels.
